Household air pollution in low- and middle-income countries: health risks and research priorities

Household air pollution (HAP), which results from incomplete combustion of the solid fuels traditionally used for cooking and heating, affects the homes of nearly 3 billion people. It is the leading environmental cause of death and disability worldwide, with highest risks for women and children due to their domestic roles. The high levels of pollutants found in HAP cause a range of diseases, in addition to burns and scalds and injuries or violence experienced during fuel collection. Additionally, household solid fuel use can pose substantive environmental risks, including degradation from fuel gathering as well as climate change from release of both CO2 and short-lived climate forcers, such as black carbon, during combustion. Despite the broad support to find solutions, only a few solid fuel interventions have shown that they might improve health over the long term, especially when implemented at the scale required (Box 1)

GenTAC registry report: Gender differences among individuals with genetically triggered thoracic aortic aneurysm and dissection

Previous data suggest women are at increased risk of death from aortic dissection. Therefore, we analyzed data from the GenTAC registry, the NIH‐sponsored program that collects information about individuals with genetically triggered thoracic aortic aneurysms and cardiovascular conditions. We performed cross‐sectional analyses in adults with Marfan syndrome (MFS), familial thoracic aortic aneurysm or dissection (FTAAD), bicuspid aortic valve (BAV) with thoracic aortic aneurysm or dissection, and subjects under 50 years of age with thoracic aortic aneurysm or dissection (TAAD <50 years). Women comprised 32% of 1,449 subjects and were 21% of subjects with BAV, 34% with FTAAD, 22% with TAAD <50 years, and 47% with MFS. Thoracic aortic dissections occurred with equal gender frequency yet women with BAV had more extensive dissections. Aortic size was smaller in women but was similar after controlling for BSA. Age at operation for aortic valve dysfunction, aneurysm or dissection did not differ by gender. Multivariate analysis (adjusting for age, BSA, hypertension, study site, diabetes, and subgroup diagnoses) showed that women had fewer total aortic surgeries (OR = 0.65, P  < 0.01) and were less likely to receive angiotensin converting enzyme inhibitors (ACEi; OR = 0.68, P  < 0.05). As in BAV, other genetically triggered aortic diseases such as FTAAD and TAAD <50 are more common in males. In women, decreased prevalence of aortic operations and less treatment with ACEi may be due to their smaller absolute aortic diameters. Longitudinal studies are needed to determine if women are at higher risk for adverse events. © 2013 Wiley Periodicals, Inc.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/97193/1/35836_ftp.pd

Identifying Patients at High Risk of a Cardiovascular Event in the Near Future Current Status and Future Directions: Report of a National Heart, Lung, and Blood Institute Working Group

The National Heart, Lung, and Blood Institute convened a working group to provide basic and clinical research recommendations to the National Heart, Lung, and Blood Institute on the development of an integrated approach for identifying those individuals who are at high risk for a cardiovascular event such as acute coronary syndromes (ACS) or sudden cardiac death in the “near term.” The working group members defined near-term as occurring within 1 year of the time of assessment. The participants reviewed current clinical cardiology practices for risk assessment and state-of-the-science techniques in several areas, including biomarkers, proteomics, genetics, psychosocial factors, imaging, coagulation, and vascular and myocardial susceptibility. This report presents highlights of these reviews and a summary of suggested research directions

Reading tea leaves worldwide: Decoupled drivers of initial litter decomposition mass‐loss rate and stabilization

The breakdown of plant material fuels soil functioning and biodiversity. Currently, process understanding of global decomposition patterns and the drivers of such patterns are hampered by the lack of coherent large-scale datasets. We buried 36,000 individual litterbags (tea bags) worldwide and found an overall negative correlation between initial mass-loss rates and stabilization factors of plant-derived carbon, using the Tea Bag Index (TBI). The stabilization factor quantifies the degree to which easy-to-degrade components accumulate during early-stage decomposition (e.g. by environmental limitations). However, agriculture and an interaction between moisture and temperature led to a decoupling between initial mass-loss rates and stabilization, notably in colder locations. Using TBI improved mass-loss estimates of natural litter compared to models that ignored stabilization. Ignoring the transformation of dead plant material to more recalcitrant substances during early-stage decomposition, and the environmental control of this transformation, could overestimate carbon losses during early decomposition in carbon cycle models

Rhythm and Orthopedics: The Effect of Music Therapy in Cast Room Procedures, a Prospective Clinical Trial

INTRODUCTION: Cast room procedures generally cause anxiety in patients. Anxiety complicates the procedure as well as increases the risk of a complication. Listening to music was found to be the safest and most common non-drug treatment method. The aim of this study is to evaluate the effect of listening to music on adult patients in cast room procedures. This study points out the relation between anxiety and anxiety relevant cardiac arrhythmia.MATERIALS AND METHODS: The study was performed on 199 patients with stable general condition, aged above 18. The patients were divided into two groups. Randomization method used in the study was coin flip. The first group (Group 1) listened to music during cast room procedures whereby the second group (Group 2) did not listen to music. Length of the procedure, complication, blood pressure and heart rate evaluations before and after the procedure, Visual Analogue Scale (VAS scores for pain), State-Trait Anxiety Inventory (STAI) anxiety score, patient satisfaction, willingness of the patient to repeat the procedure, P wave dispersion (Pd) and corrected QT interval dispersion (QTcd) as electrocardiographic arrhythmia predictors were evaluated. The Clinical Research Ethics Committee approval was obtained for this study.RESULTS: Significant difference was shown between the two groups for the following criteria: VAS scores (p = 0.005), anxiety scores (p = 0.032), processing time (p = 0.027), and QTcd values (p = 0.031). Patient satisfaction (p CONCLUSION: Music therapy is a non-invasive, safe, nonpharmacologic, anxiolytic, and analgesic treatment. Music therapy should become standard protocol in cast room procedures. One of the most important achievements of this study was the fact that music decreases anxiety and anxiety-related cardiac arrhythmia. Therefore, conducting further prospective studies including high cardiac risk patients especially with arrhythmia is crucial

Assessment of central venous catheterization and complications in a tertiary pediatric intensive care unit

PubMedID: 30102481In catheter-using units as pediatric intensive care, it is important to know the complications that may occur during the insertion and use of central venous catheterization (CVC), and to take appropriate measures in order to reduce the mortality and morbidity of critical patients. The aim of this study was to evaluate CVC and catheter related complications in our tertiary pediatric intensive care unit. For this prospective study, 155 central venous catheters and/or hemodialysis catheters used with 106 patients, between August 2014 and August 2015 were evaluated. Demographic information about patients, catheter insertion procedure and catheter related complications were recorded. Sixty-two (58.5%) male and forty-four (41.5%) female patients were evaluated in this study. The median age was 67.5 months (1-212). The mean dwell time of catheters was 10.54±8 days. Twenty-two (14.2%) catheters were removed from patients because of catheter related complications. The mean dwell time of complicated catheters was 10.6±8.5 days and there was no statistically significant difference between complicated and non-complicated catheters. Catheter related blood stream infections was diagnosed in 5.1% (8/155) patients and these catheters were removed from patients. Including these patients, positive blood culture was found to be at 14.2% (22/155). The mean dwell time of catheters with positive blood culture was 14.25±7.3 days. The mean dwell time of catheters with positive blood culture was statistically significantly longer than catheters with negative blood culture. In the 3 patients who developed catheter thrombosis, 2 patients were followed up because of infection/sepsis and 1 patient had a neurological disease. Catheter thrombosis developed in 1 femoral vein and 2 internal jugular veins. The development of central venous catheter complications depends on many different factors and it is possible to reduce the complications with precautions taken during replacement and daily use. © 2018, Turkish Journal of Pediatrics.

Can serum biochemical markers be used to establish a relationship between idiopathic polyhydramnios and antenatal aneuploidy?

Background: Polyhydramnios is a common cause of adverse pregnancy outcomes. The prediction of polyhydramnios in early pregnancy may lead to improved treatments and will diminish these adverse outcomes. Objective: This study aims to investigate the role of biochemical markers in antenatal screening tests to predict idiopathic polyhydramnios. Methods: Patient records were retrospectively evaluated in this case-control group study. Pregnant women (160 in total) were included in the study (this included 47 pregnant women diagnosed with idiopathic polyhydramnios and 113 healthy pregnant women as a control group). Results: Alpha-fetoprotein, unconjugated estriol, and total beta-human chorionic gonadotropin values were similar in both groups (p = 0.296, p = 0.573, p = 0.284). There was no significant difference between the group diagnosed with idiopathic polyhydramnios and the control group when the first-trimester screening test parameter, pregnancy-associated plasma protein-A, was examined (p = 0.102). Conclusion: Biochemical markers examined in prenatal screening tests in the first and second trimesters were insufficient to predict idiopathic Polyhydramnios. The reasons for this are that our study was retrospective, and the patient population was low. We believe that a prospective study with a larger population of patients should be conducted for more meaningful results
